3. Position the power cord so that people cannot step on it. Do not place anything
over the power cord.
4. Always completely disconnect the power before working on the system’s
hardware.
5. No connections should be made when the system is powered as a sudden rush
of power may damage sensitive electronic components.
6. If the device is not to be used for a long time, disconnect it from the power
supply to avoid damage by transient over-voltage.
7. Always disconnect this device from any AC supply before cleaning.
8. While cleaning, use a damp cloth instead of liquid or spray detergents.
